- There is no formal resolution on containers yet. There has been some discussions, and deprecating containers has indeed been raised as one of the candidates.

- However, your usage of rdfs:member v.a.v. lists (a.k.a. collections) is a slightly different question. At them moment, there is no semantic relationships in RDFS between the terms used for lists (rdf:first, rdf:next, or rdf:List) and rdfs:member. Put it another way if I have 

<a> <b> (<c> <d> <e>) .

I cannot infer something like

<c> rdfs:member _:a . # _:a is the 'head' of the list above.

I may have misunderstood what you said, though.
